[PATCH] afs: Return -EAGAIN, not -EREMOTEIO, when a file already locked

From: David Howells
Date: Wed Aug 17 2022 - 13:33:47 EST


When trying to get a file lock on an AFS file, the server may return
UAEAGAIN to indicate that the lock is already held. This is currently
translated by the default path to -EREMOTEIO. Translate it instead to
-EAGAIN so that we know we can retry it.
